I think he's mostly looking at the shady circular financing we've been hearing about and that the energy requirements necessary for the growth projections of AI are years away while the AI companies are acting like it's months away. With those 2 things AI is going to trip in the much nearer future than the market disruption from AI taking jobs from people.
Or at least that's my read on his analysis. I share those 2 concerns, but I have no idea on how the timing will work out and I think that's pretty key on whether or not Burry's bet pays off or not.
